为什么海洋热含量是气候变化最可靠的指标之一？
Why is ocean heat content one of the most reliable indicators of climate change?
海洋吸收了气候系统九成以上的新增热量，其热含量变化受年际波动影响小、对辐射强迫响应稳定，比地表气温更能代表地球能量失衡。Argo浮标阵列提供了全球深海温度的连续观测。
The ocean absorbs over 90% of the climate system's added heat; its heat content varies little year-to-year and responds stably to radiative forcing, making it a better measure of Earth's energy imbalance than surface air temperature. The Argo float array provides continuous global subsurface observations.

海洋「生物泵」如何将碳从表层输送到深海？
How does the ocean's biological pump transport carbon from the surface to the deep sea?
浮游植物光合作用固定CO2，死亡后形成颗粒物沉降至深海，部分被微生物分解、部分埋入沉积物，从而将碳从大气端隔离到深海。该过程效率受营养盐供给与食物链组成调控，是海洋长期碳汇的核心机制。
Phytoplankton fix CO2 by photosynthesis; when they die, particles sink to the deep ocean, where some are remineralized by microbes and some are buried in sediments, sequestering carbon away from the atmosphere. Efficiency is regulated by nutrient supply and food-web structure and is central to the ocean's long-term carbon sink.

大西洋经向翻转环流（AMOC）对全球气候有何关键作用？
What critical role does the Atlantic Meridional Overturning Circulation (AMOC) play in global climate?
AMOC将表层暖水北送、将深层冷水南返，向高纬度输送大量热量，是西欧气候温和的重要原因。其减弱会改变热量与碳的经向输送，并可能触发区域降温与海平面重新分布。
The AMOC carries warm surface water northward and returns cold deep water southward, transporting enormous heat to high latitudes and keeping Western Europe mild. Its weakening would alter meridional heat and carbon transport and could trigger regional cooling and sea-level redistribution.

厄尔尼诺事件期间热带太平洋海表温度与环流如何变化？
How do tropical Pacific sea-surface temperature and circulation change during El Niño?
厄尔尼诺期间赤道东太平洋海表异常增温，东西太平洋温差减小，信风减弱，暖池东移并抑制西太平洋降水、引发东太平洋上升流减弱。这通过大气遥相关影响全球天气与渔业。
During El Niño the equatorial eastern Pacific warms anomalously, the east-west temperature gradient shrinks, trade winds weaken, the warm pool shifts east, and upwelling off the eastern Pacific fades. Through atmospheric teleconnections this reshapes global weather and fisheries.

海洋中的缺氧带（死区）是如何形成的？
How do oxygen-minimum zones (dead zones) form in the ocean?
富营养化使表层藻类暴发性生长，其死亡下沉后被细菌分解耗尽溶解氧，加上层化抑制垂直混合，在陆架与海湾形成低氧或缺氧区。这类死区威胁鱼类生存并释放温室气体氧化亚氮。
Eutrophication fuels algal blooms whose sinking detritus is decomposed by bacteria that consume dissolved oxygen; with stratification limiting vertical mixing, low- or no-oxygen zones form over shelves and bays. Such dead zones threaten fish and can release nitrous oxide, a greenhouse gas.

人类排放的二氧化碳如何导致海洋酸化？
How does human CO2 emission lead to ocean acidification?
约四分之一人为排放的CO2被海水吸收，与海水反应生成碳酸并释放氢离子，降低海水pH值。自工业革命以来表层海水pH已下降约0.1单位（酸度增加约30%），影响珊瑚与贝类的钙化。
About a quarter of anthropogenic CO2 is absorbed by the ocean, where it forms carbonic acid and releases hydrogen ions, lowering seawater pH. Since the industrial revolution surface pH has fallen about 0.1 units (roughly 30% more acidic), impairing calcification in corals and shellfish.

格陵兰与南极冰盖融化可能对洋流产生什么影响？
What effect might Greenland and Antarctic ice-sheet melt have on ocean currents?
大量淡水注入北大西洋会削弱海水下沉，可能减缓AMOC；南极融水则影响绕极流与底层水形成。这些变化会改变区域气候与海平面分布，是未来气候情景的重要不确定源。
Large freshwater input to the North Atlantic can weaken sinking and slow the AMOC; Antarctic melt affects the Antarctic Circumpolar Current and bottom-water formation. Such changes would reshape regional climate and sea-level patterns and are a major uncertainty in future scenarios.

什么是蓝碳，沿海生态系统为何是重要的碳汇？
What is blue carbon, and why are coastal ecosystems important carbon sinks?
蓝碳指红树林、盐沼和海草床等沿海生态系统捕获并长期埋藏的碳，单位面积固碳速率常高于陆地森林。它们通过植物光合固定的有机碳在沉积物中可保存千年，对减缓气候变化有独特价值。
Blue carbon is the carbon captured and buried long-term by coastal ecosystems such as mangroves, salt marshes, and seagrass meadows, whose per-area sequestration rates often exceed those of terrestrial forests. Photosynthetically fixed organic carbon can persist in sediments for millennia, offering unique climate mitigation value.

什么是雷维尔因子？它为何说明海洋吸收人为CO2的能力有限而且还在下降？
What is the Revelle factor, and why does it mean the ocean's capacity to absorb anthropogenic CO2 is limited and still shrinking?
海水中的溶解无机碳主要以碳酸氢根形式存在。新溶入的CO2会与碳酸根结合生成更多碳酸氢根，使游离CO2的相对增幅远大于总溶解无机碳的增幅，这一缓冲效应由雷维尔因子度量，现代海水约为10：大气CO2分压要升高约10%，表层海洋含碳量才增加1%。随着排放累积、酸化消耗碳酸根，海洋吸收CO2的化学容量还会进一步缩小。
Most dissolved inorganic carbon in seawater exists as bicarbonate. Newly absorbed CO2 reacts with carbonate ions to form yet more bicarbonate, so free CO2 grows proportionally far faster than total dissolved inorganic carbon - a buffering measured by the Revelle factor, about 10 today: atmospheric CO2 must rise roughly 10% for surface-ocean carbon to increase only 1%. As emissions accumulate and acidification consumes carbonate, this chemical uptake capacity keeps shrinking.

为什么赤道太平洋总体向大气净释放二氧化碳，而亚极地北大西洋却是净吸收区？
Why is the equatorial Pacific a net source of carbon dioxide to the atmosphere while the subpolar North Atlantic acts as a net sink?
二氧化碳在冷水中的溶解度明显高于暖水。赤道海域水温高，且信风驱动下层富碳海水上翻，使表层二氧化碳分压高于大气，故净释放；亚极地冷水溶解能力强，春季浮游植物光合作用又快速消耗碳酸盐体系中的碳，表层分压随之降到大气之下，转为净吸收。这种冷暖格局叠加生物泵，奠定了全球海气碳通量分布的基础。
Carbon dioxide dissolves much more readily in cold water than in warm. In the equatorial Pacific, warm surface waters plus trade-wind-driven upwelling of carbon-rich deeper water push surface pCO2 above atmospheric levels, so the ocean outgasses net. In cold subpolar seas strong solubility and springtime phytoplankton photosynthesis draw surface pCO2 below that of the air, making the region a sink. This warm-source, cold-sink pattern, modulated by the biological pump, anchors today's maps of global air-sea carbon flux.
